I'm trying to get the pcHDTV 5500 working under gentoo 2.6.18 with the built-in drivers. I am unable to test the ATSC side of things at the moment, but the NTSC side gives me nothing but static. The machine is a Core 2 Duo (x86_64). I've been reading these forums for a while trying to find an answer, but I can't find anything.

Let me know what other information would be of the most use, e.g. kernel config.

The output from dmesg would be good for a start.

Here's a the dmesg output concerning the tuner cards. Let me know if you need the whole thing. I am testing using mplayer.

Do you have two PCHDTV 5500s? If not, something's wrong... the card is showing up twice.

(never mind, I see you say "cards")

The usual NTSC issue is the dvb_shutdown_timeout parameter to the dvb-core module needs to be set to 0 in a file in /etc/modprobe.d

I've got the following in /etc/modules.d/dvb-core

Code:

options dvb-core dvb_shutdown_timeout=0

Have you tried using tvtime for viewing NTSC broadcasts?

As far as ATSC goes, I use dvbstream to capture broadcasts (and then dtvstream to clean up broadcast errors) and mplayer to view recorded content.

What type of problem do you have with ATSC? Do you have devices in the directory:

Code:

/dev/dvb/adapter0

?

Do you have any errors generated on the command line or in your dmesg output when you attempt to tune a station?

I don't know if I'm having any problems with ATSC, I don't have an ATSC source hooked up yet. I want to make sure I get NTSC first. Plus, the ATSC tools I have need to scan for the channels before they'll let me see if I've got anything.

If you can receive a NTSC signal OTA, then you can probably also receive an ATSC signal. Unless you are trying to use cable as the source.

I am using cable as the source. I intend to use cable as the ATSC source later, but I need to be sure I've got the cards working before I switch to digital cable.

I am having the same problem

Nothing but static on tvtime for NTSC. I am using a 64-bit kernel; not sure if that matters.

Hmm. I'm out of easy answers. Have you tried just one card at a time? Have you made sure a regular TV works with the particular cable you are using?

The cable signal is fine, it works with my TV and my old gentoo box (PVR-350 card). I'm trying to get this up-and-running so I can retire that machine in favor of this new one. I am beginning to wonder if this is a 64-bit issue. I used the recommended -march=nacona when compiling, is this perhaps an issue?

I'm running 64-bit Ubuntu (2.6.15 and 2.6.17 on different boxes) myself, but AMD rather than Intel.

I only have one card here, on an amd64 box. Here's the cx88 stuff I'm seeing:

One thing I did notice is that the card type is "TV tuner 64" which isn't listed in the v4l table. Seems like this should be 47 (from cx88.h, which is CX88_BOARD_PCHDTV_HD5500).

I also get these errors periodically, not sure what the problem is there:

Code:

Nov 23 12:27:25 potato cx88[0]/2: cx8802_timeout

Also tried this with 2.6.19-rc5; same problem.

Solved!

I found the problem!

You MUST load the 'tuner' module as well as the cx88xx module, and you should specify 'tuner=47' as a parameter to the cx88xx module. Works fine then through tvtime for UHF. I'm now looking at VHF, although I don't see why that should be a problem.
